Defending champion Florida is heading back to the College World Series. The Gators clinched their spot in Omaha in the most thrilling — or agonizing — way possible.

Austin Langworthy hit a walk-off solo home run in the 11th inning off right fielder Steven Williams' glove to give Florida a 3-2 win over SEC rival Auburn in the deciding game of their super regional Monday night.

Langworthy led off the 11th with a line drive to deep right off freshman All-American closer Cody Greenhill. Williams tracked it to the wall and jumped on the warning track. He appeared to have a good chance to make the play, but the ball bounced off his glove and over the wall for the deciding run.

"It's unbelievable," said Langworthy, who was robbed of extra-base hits by diving catches in his previous two at-bats. "I think in this game everything comes back to you. That’s how this game works."

Williams hung his head and crouched on the warning track in disbelief. As Williams collected himself, the entire Auburn team walked out to right field to console him.

"It won't define him," said Auburn head coach Butch Thompson. "It will be part of his journey."

Top-ranked Florida (47-19) returns to the College World Series for the fourth consecutive year and the seventh time in the last nine years. The Gators won the first national championship in program history last season.

Auburn (43-23) was trying to get back to Omaha for the first time since 1997. The College World Series begins Saturday at TD Ameritrade Park. Florida plays Texas Tech in its first game on Monday.
